Tradie quotes were outrageous, so I gave this liquid rubber a crack. Prep was key. cleaned the wall and let it dry. Applying it was easy, like thick painting. Saved me a few grand. If you can paint, you can do this. Highly recommend!

Retaining Wall Waterproofing FAQs
Can I apply Liquid Rubber over existing coatings or sealants?
For the best waterproofing results, apply Liquid Rubber to a clean, dry surface. Remove loose or peeling coatings, silicone, rust scale, and other contaminants first. This ensures maximum adhesion and long term leak protection.
What tools and equipment do I need to waterproof my roof?
Application is simple. Use a paintbrush, roller (included in our kits), or a spray machine for larger Tanks. Basic safety gear such as gloves is recommended, and keep a suitable cleaner handy for spills and tool cleanup.
What is the best way to prepare the surface for application?
Use a power washer to clean the surface. The surface must be clean, dry, and free of debris, mold, and other contaminants.
